Thermal management is a critical challenge for the deployment of battery systems, due to their highly dynamic operation and wide range of operation environments. For example, the optimal temperature range of operation (~20 to 40 deg. C) can be dramatically narrower than the operation range (which can vary between ~70 to -40 deg. C).
This project addresses four topics in the area of powertrain thermal management: 1) establishing an experimental platform to demonstrate and study thermal management strategies, 2) developing and validating multi-disciplinary models integrating heat transfer, fluid mechanics, and electro-thermal dynamics, 3) demonstrating and exploring control strategies to maximize the cooling performance and minimize parasitic power consumption, and 4) continuing and augmenting our collaborations with other PIs and quad members.
The end goals of this effort are twofold: 1) demonstrate control strategies to maximize cooling performance and minimize parasitic power consumption, and 2) apply these strategies to design and optimize cooling systems at a subsystem-level.
This projects collaborates with ARC researchers in the areas of battery thermal modeling, thermal issues of e-motors, integration of battery cooling sub-system in the overall powertrain control and optimization framework.
